Using a drip system of coolant I found also helps on keeping sliver chips from dusting everything. They all stay in the mud from the cutter that you catch with the rag trick. Any that flow with the coolant into the table, you can toss a small magnet in where it is pooling. Dont try and clean the magnet, just remove it to sop up whats sitting.
A drip hose can be made easy with a coffee can wired to the head of the machine and a small valve or C clamp to the tubing. Run the tubing down to the arbor twist tied on a stem, let the gravity flow and adjust the drips with the clamp.
Slitting saws are notorious for them kind of chips. Always if you can slow the rpms down or the feed up to stay below the chatter, thats where the chips originate. If the cutter is quiet, you know your rolling a chip, and not spiking one. You get tolerable chips and the cutter is working like it should, which keeps it sharp.
